Covid19: A case for medical detectives

The numerous and disproportionately frequent deaths of Covid19 patients with dark skin colour and from southern countries are apparently also the result of a drug-related mistreatment. Those affected are people with a specific enzyme deficiency, which occurs mainly in men whose families come from regions where malaria was or still is endemic.They are currently being treated with hydroxychloroquine, a drug which they do not tolerate, now being used all over the world to fight Covid-19. If this practice does not end soon, there is a great risk of widespread deaths, especially in Africa.
